If the secondary voltage is 250 v then current will be according to ohms law V = IR that is 250/1000 = 0.29 A.

I=V/R.
=50/1000,
= 0.005,
And ratio is 1:5.
Therefore 0.005*5=0.25=250mA.

According to ohms law. V=IR.

I = V/R.

I =250/.

= 250.

So the given answer is correct.

Given v1=50v, r2=1kohm,

N1:N2 = 1:5.

v2/v1 = N2/N1.

So v2 = 50*5/1 = 250V.

I2= v2/r2 = 250/1000 = 250mA.

Vs=Ns/Np.Vp
Vs=5/1*50
Vs=250
Vs=IR
250/1=I
I=250

Its very simple.

According to ohms law. V=IR.

So I=V/R. I=250/1 = 250.
